Abstract
Clothing is provided for a machine for producing a fibrous web, in particular a paper, board or tissue web. The clothing has a substrate. The substrate has a top side, an underside, two side edges and a useful region between the two side edges. The useful region has a plurality of through-channels, which connect the top side to the underside of the substrate. An inner surface of at least one through-channel, preferably of the majority of all the through-channels, more preferably of all the through-channels in the useful region of the substrate, has a mean roughness depth that is greater than 4 μm, preferably greater than 6 μm, more preferably greater than 8 μm. The clothing of this type is produced using a laser.
